We've decided to go our own route DJ-wise and use our iPod as the music for the wedding reception. I'm creating a playlist to span the whole evening, so we can just hit "play" in the beginning and let it go. We're going to have quite an ecclectic mix of people at our reception, with music tastes ranging from classic rock to rap to dubstep. Any advice on particular songs we should include and how exactly to mix the styles? Also, what's the best ratio of slow songs to fast songs? Any advice my fellow knotties can give me is much appreciated!
